HVAC Psychrometry, Air Handling System and Duct Selection from Udemy

*Free summary PDF file included*

If you're new to the HVAC industry or seeking to broaden your understanding in this intricate and often challenging field, you've found the perfect place.

Our training approach emphasizes simplifying key concepts to make them easily understandable. In this course, we extensively cover the air side of building air conditioning systems, guiding you step-by-step towards proficiency in evaluating, selecting, and sizing Air Handling Units (AHU) and Air Ducts.

By leveraging fundamental mechanical engineering principles such as thermodynamics, heat transfer, and fluid mechanics, you'll be able to convert theoretical knowledge into practical skills relevant to the HVAC sector. Topics we explore include psychrometry, the equal friction method for duct sizing, analyzing heat gain in spaces, and even control applications using Building Management Systems (BMS).

Enroll in this course to get a head start in your HVAC career.
